'Parks and Recreation' back on Thursdays

For three weeks, this clever comedy sat on the shelf while NBC pondered its shaky Thursdays. Now it's back and will double its episodes, starting with the key ones about Leslie fighting a recall vote. In tonight's first episode, she throws Ben a birthday party, then is called away for a filibuster. In the second, she faces the recall vote on Halloween - a reminder that this was supposed to air sooner.
